Heavy Duty Positioning Arms


Arm Built with Floor- and Bench-Mount Pole Base, Pole, Pole-to-Pin Adapter, Two Rigid Connectors, and Pivoting Mounting Plate	Arm Built with Wall-Mount Pin Base, Two Rigid Connectors, and Pivoting Mounting Plate

Heavy duty construction adds strength for higher load capacities than other positioning arms. Choose a complete arm or select a base, connectors, and plate, bracket, or tray to build a complete arm. The load capacity of an assembled arm is determined by the component with the lowest capacity.

With strength for higher load capacities than other ball-grip positioning arms, these arms have a heavy duty construction. Ball-and-socket connections allow 360° positioning. The base, connectors, and links are hollow for routing wires, cables, and small hoses. Select a base, connectors, link, and plate or mount to build a complete arm. Capacities are based on an assembled arm that is 1 foot long.

Blank Mounting Plates

Mounting plates require a base and a straight or tee connector to attach to a link. Blank mounting plate allows you to drill custom mounting holes.

Suspension Positioning Arms for Enclosures


Example Configuration	All Components Sold Separately

Example Configuration

Hang your human-machine interface and swivel it around to save floor space and comfortably access touch screens, buttons, and other operating equipment. These suspension arms have already-drilled mounting holes that match our HMI enclosures. Route wire from your HMI components to a machine through a hole that runs through the entire arm. To prevent them from swinging too far and hitting people and equipment, locking pins let you restrict how far these arms rotate. Brakes lock their position into place.

Customize a system for your application—you can create hundreds of different variations. A complete suspension arm requires at least a base, a tube, and a mount. Add components to extend your arm up to 80” from the base and expand its range of motion. Arms without a connector support up to 180 lbs. Those with a connector support up to 135 lbs., but the load it can hold decreases by 2 lbs. for every 1” over 40” from the base.

Bend-and-Stay Positioning Arms

Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.

All accessories include the necessary hardware for attaching them to arms.
